Bartonellosis remains a major problem in Peru, but many contemporary aspects of this disease have not been adequately described. We examined the cases of 145 symptomatic patients in Lima, Peru, in whom bartonellosis was diagnosed from 1969 through 1992, including 68 patients in the acute (hematic) phase and 77 patients in the eruptive (verruga) phase. In modern Peru, symptomatic patients who ha...

Raw or inadequately cooked pork is an important source of Toxoplasma gondii infection, and the infection rate in animals used as human food, is an important risk predictor. The prevalence of this infection was estimated in 396 sera from 5-month old pigs obtained at abattoirs in São Paulo, Brazil (300) and Lima, Peru (96). The seroprevalence was higher in pigs from Peru (32.3%) as compared to Br...

This paper examines – for two developing countries, Vietnam and Peru – whether disadvantaged children learn less than advantaged children when both types of children are enrolled in the same school. This is done by estimating education production functions that contain two school fixed effects for each school, one for advantaged children and one for disadvantaged children. The paper examines si...

Contents of eight mineral elements in maca (Lepidium meyenii Walp.) from China and Peru were determined by inductively coupled plasma optical emission spectroscopy. Cu contents in maca samples from China (2.5-31 mg kg(-1) dry weight, dw) were higher than the samples from Peru (<2.1 mg kg(-1) dw). Na in two samples from China was found to be significantly of high content (2400 and 2600 mg kg(-1)...

Carrion's disease is caused by infection with the alpha-proteobacterium Bartonella bacilliformis. Distribution of the disease is considered coincident with the distribution of its known vector, the sand fly Lutzomyia verrucarum. Recent epidemics of B. bacilliformis infections associated with atypical symptomatology in nonendemic regions have raised questions regarding the historic and present d...

Two new species of lizards assigned to the genus Euspondylus from the montane forests of the Peruvian Andes in the Pasco Department (central Peru) and Ayacucho Department (southern Peru) both at elevations of 2550 and 3450 m, respectively, are described. The new species are distinguishable from all other Peruvian and Ecuadorian species of Euspondylus by a unique combination of morphometric, sca...

A new species Rhodorhipha dalyi sp. nov. from Peru (Tambopata river, Madre de Dios, Peru) is described and illustrated. The part of a complex similar related to R. subflammans (Rothschild).

Coendouichillus was first described in 2001 by Voss and da Silva, with a range from Amazonian Ecuador to Iquitos, Peru. Here, we describe an adult female Coendouichillus specimen collected in a Tomahawk trap in the forest canopy of the Lower Urubamba Region of Peru in October 2013. We also describe pathologies and behaviors observed through 379 camera trapping photo events (2,196 photos) gather...

In 2001, Peru changed its treatment policy for uncomplicated Plasmodium falciparum malaria on the northern Pacific Coast to sulfadoxine-pyrimethamine with atresunate (SP-AS). Because Peru was the first country in the Americas to adopt this combination therapy, we established a surveillance system in the region to assess the frequency of new or worsening symptoms after starting therapy. Over a p...
